Question

The unit of electric field is not equivalent to

• A. N/C
• B. J/C
• C. V/m
• D. J/C-m

Answer 1

The correct option is B J/C

By unit and dimension - electric feild.

$\frac{N}{C}=\frac{volt}{meter}=\frac{J}{c-mt}$

Therefore, dimensions of $E=ML{T}^{-3}{A}^{-1}$

which is a vector quantity.

So, the correct answer is $B:J/C$

Because, it gives the answer work done per unit charge which is called Potential.
